@Bsmith Technically, since she was the "captive" it's Lima Syndrome. Though in this case I'd make a strong argument that they were in fact trapped in there with her, swinging it back around to Stockholm Syndrome.
Perhaps the situation is enough of an aberration to come up with a name of its own.
So when someone tries to rape you, the appropriate punishment is to beat them up a little and all is well and forgiven and you sit down and play card games?
Dang, the best joke in the novel got lost in adaptation. Our brave hero has years of experience playing card games with other bored holy knights. There’s no way she’d lose to these scrubs.
